Enjoy Exercise and Reading Simultaneously! "Mimi-katsu Walking" Attracting Attention in Dementia Prevention Research

Mimi-katsu Walking is a new habit of walking while listening to audiobooks.

It is drawing attention for its ability to solve problems such as "can't stick to exercise" and "don't have time to read" simultaneously. Furthermore, research conducted by Otobank and Kansai University of Social Welfare has shown that moving the body while listening to audiobooks can activate brain blood flow to the same extent as brain training for dementia prevention (※2).

The Mimi-katsu Walking campaign was first held in 2023 and received positive feedback, and this year marks its 4th occurrence.

Users who experienced Mimi-katsu Walking commented:

"Normally I listen during my commute, but I started walking on weekends too, and it was fun."

"It became an impetus to walk almost 10,000 steps every day."

"By combining regular walking with reading by ear and making it a habit, I was able to lead a healthy life."

We hope this campaign will be an opportunity to enjoy exercise and reading in this beautiful season of fresh greenery.

Service Collaboration Project to Expand the Circle of "Mimi-katsu Walking"!

Since April 2025, audiobook.jp has opened an official challenge within the habit-forming app "Minchare" operated by Aten Lab Inc. By joining a "team" of 5 people and sharing the works listened to and the distance walked, users can enjoy "Mimi-katsu Walking" and connect it to habit formation for exercise and reading.

Also, in 2026, a first-time collaboration campaign with CLAS (furniture and appliance rental/subscription service), titled "Mimi-katsu Walking at Home! with CLAS," will be held simultaneously. CLAS will introduce recommended items that make exercise more comfortable, including indoor walking machines. This supports creating an environment where people can enjoy a healthy "Mimi-katsu" lifestyle at home.
